In the interior of Amazonas, the phenomenon of 'fallen lands' is becoming a significant concern as the rising water levels from the rivers lead to landslides that threaten both homes and farmland. Residents in the rural municipality of Careiro da Várzea are accustomed to this problem, enduring the risks every year without considering relocating permanently. Instead, they adapt their living situations by physically moving their homes further away from the banks of the river to mitigate the dangers posed by the ever-changing landscape.

In one of the affected communities, Praia da Justina, the history of numerous families has been washed away by the advancing waters of the Rio Amazonas. José Guedes, a local farmer, shares that since his family's arrival in 1954, they have witnessed a substantial loss of 500 meters of land to erosion caused by the river. Guedes highlights the mental and emotional strain of living with the knowledge that their homes are at risk, particularly those situated near water channels, which become perilous during flood seasons when the current can sweep homes away.

According to geologist Iris Celeste Nascimento Bandeira, such events are unavoidable in many segments of the river due to natural processes; thus, the residents must continue to adapt and find ways to protect their homes and livelihoods. This ongoing reality raises questions about the long-term impacts of climate change and shifting environmental conditions on local communities, as they face increasingly dire challenges to their survival and ways of life in the face of nature's forces.
